The best position for the client when applying elastic stockings is lying down in bed. This position helps ensure that the legs are relaxed and that there is minimal tension in the muscles and veins. When the client is lying down, it is easier to accurately measure and apply the stockings without causing discomfort or constricting blood flow.

Additionally, applying the stockings while the client is lying down allows for proper venous return, which is essential for patients who may have circulation issues or are at risk for deep vein thrombosis. This position also minimizes the risk of injury or falls since the client is in a stable position.

In other positions, such as sitting upright or standing, there may be more strain placed on the legs, which could affect the ability to correctly apply the stockings and could lead to complications. For example, sitting or standing might cause the legs to swell, making it more difficult to fit the stockings properly. Thus, lying down is the optimal choice for both the comfort of the client and the effectiveness of the stocking application.
